This so far is my favorite alternative process! The contrast that you are able to achieve by using a digital negative and the sun as your processor is just amazing. I have done many more cyanotypes, however these are my favorites. I am interested in doing more portraits using this method, I love the way the skin tones expose. They are also challenging as to not wash out the hightlights of the entire face. This portrait was the most successful in achieving more of a value range.
